Swinglets

Program your JPS & Servlets like you program your Swing components. Swinglets is a server side component library that uses an identical design to Swing. Swinglets has look and feels for HTML, Java Script and WML.
The Components, Models, Renderers, and LookAndFeels are very similar. It has Swing event handling too. In fact Swinglets actually uses the Swing models (e.g. TableModel). This means you can take your existing models and start working with Servlets straight away. It's just about as close to a standard as you can get without it actually coming from Sun themselves.
